• Fix kubernetesClient.resources(HasMetadata.class).inNamespace("default").withLabels(Map.of("foo", "bar").list() throws NullPointerException #3990: Throw exception when HasMetadata is used in resources(...) API
• Fix withResourceVersion off of collection problems with waitable #4081: moving Versionable.withResourceVersion to a method on WatchAndWaitable and removing Waitable from the return type
• Fix Projectrequests should not be listable #4106: removed listing from projectrequests
• Fix Rolling operations issues #4140: changed StatefulSet rolling pause / resume to unsupported. Also relying on default rolling logic to Deployments and StatefulSets

• Fix Why is KubernetesDeserializer in a package named "internal"? #1285: removed references to manually calling registerCustomKind
• Fix Missing cancellation support in LeaderElector #2207: added LeaderElector.start to provide a CompletableFuture for easy cancellation
• Fix Add support for Server Side Apply #3334: adding basic support for server side apply. Use patch(PatchContext.of(PatchType.SERVER_SIDE_APPLY), service), or new PatchContext.Builder()withPatchType(PatchType.SERVER_SIDE_APPLY).withForce(true).build() to override conflicts
• Fix Annotator code for main model and extension model modules should be merged #3486: using a common jsonschema2pojo annotator - see the migration guide for possible changes to extension models
• Fix HasMetadata should have convenience methods for annotations and labels #3625: adds default maps to mostly prevent the need for null checks on things like annotations and labels

  SharedIndexInformer allows for the addition and removal of indexes even after starting, and you can remove the default namespace index if you wish.
  And Store.getKey can be used rather than directly referencing static Cache functions.
• Fix onUpdate is called on re-list even if resourceVersion is unchaged #3969: relist will not trigger sync events
• Fix Add a method to get the core/legacy apiresources #4065: Client.getAPIResources("v1") can be used to obtain the core/legacy resources
• Fix informOnCondition should not test initial add events #4082: improving informOnCondition to test the initial list instead of individual add events

  There is also client.resourceList(...).resources() and client.configMaps().resources() - that will provide a Resource stream.
  This allows you to implement composite operations easily with lambda: client.secrets().resources().forEach(r -> r.delete());
• Fix Make it possible to customize Informer Cache key function  #3472 Add a construct in between a Watch and an Informer #3587: Allowing for customization of the Informer store/cache key function and how state is stored. See BasicItemStore and ReducedStateItemStore and the SharedIndexInformer.itemStore function

Hi,

Do you have some staging repo with the Maven artifacts which can be used for testing? Or does it need to be built and distributed locally?

Thanks & Regards
Jakub

Great, thanks. (And sorry for the dumb question - I somehow didn't realised that it is already in Maven Central)

There are no dumb questions, no worries. Just remember to provide feedback, yours is especially valuable ;)
